EUV light

Extreme Ultraviolet Lithography light

A method of using shorter wavelengths of light to create smaller circuits. Current technology uses light waves about 240 nanometers long (so-called deep ultraviolet light) to create circuits about 100 nanometers wide (a nanometer is one-billionth of a meter). If scientists succeeded with EUV light, circuits could shrink in width to 10 nanometers, which in turn could make microprocessors 100 times more powerful.
